ABSTRACT:
An electromagnetic clutch with an improved rotor, and a method of manufacturing the rotor includes the steps of: (a) forming a cup-shaped blank with a generally cylindrical flange wall and a bottom plate by bending a piece of sheet metal; (b) forming at least one approximately V-shaped groove in the blank flange wall by a pressing operation; (c) forming a final V-shaped groove by applying a roller working operation to the approximately V-shaped groove; and (d) welding an inner cylindrical member to a radial inner surface of the bottom plate of the cup-shaped blank.
